About versions: http://elrepo.org/tiki/kernel-ml
About the discussion about KVER: Im not blaming the misworking module, I
want to understand why its wrong and try to see what we can do about this.
4.5.0 indeed is STABLE kernel and well, its a good thing to know if it
changes the API or something else. Anyways, the discussion about module
"working" is (at least for me now) not valid since after what I pasted
below, *** i think its a compilation environment issue*** (And a dkms.conf
miswriting, since Im not a master of dkms or kernel development). So, my
new attempt is documented below. Someone can please, instead blaming kernel
or just saying its supported or not, try to show to me what is happening
and - if someone know how to make it better, write informations about how
this can be done?
A "progressive regression": in dkms.conf, changing "MAKE="cd src/; make
BUILD_KERNEL=\${kernelver} noisy"" to "MAKE="cd src/; make
KVER=\${kernelver} noisy"" - the module compiles, but vermagic is from old
kernel. Its ok?
